CATTLE-'GUAILD-OIERATING- MECHANISM.

I s ecification of Letters Patent. Patented Aug. 23, 1910.

Application filed November 5, 1909. Serial No. 526.451.

To all irhom it may concern- Be it known that I, VTLLIAM TERRY, a citizen of'the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Cattle-Gizard-Operating Mechanism, of which the following is 'a'specification. r

This invention relates to cattle guards 'of that type designed to be used along railroad tracks and its object is to provide a device of this character which is normally in a posit on to prevent livestock from leaving an inclosure by way of the railroad track passing therethrough. simple means being utilized whereby the saidguard willbe auto matically opened by a train approaching the same.

Another object is to provide means for' guard actuating frame and showing the guard in elevation. Fig. 2 is a plan view of the complete apparatus.

Referring to the figures by characters of reference 1, 1 designate fixed posts located beyond opposite sides of the track 2, each of these posts being provided with one or more horizontal guide rods 3 extending in the direction of the track, there being a guide standard 4 between the track and each set of rods 3. Each standard 4 is preferably in the form of an elongated yoke having guide eyes 5 at its upper end within which are slidably mounted parallel top rods 6 constituting the upper portion of a gate A. These rods are secured at their ends to end strips 7 and additionalparallel rods 8 connect the said end strips. One of the end strips 7 has apertures therein through which the rods 3 extend, there being heads 8 upon the free ends of said rods so as to limit the movement of the strips 7 in one direction thereon. One or more springs 9 connec the apertured strips 7 with the adjoining standard 4, these springs serving to hold the gate A normally removed from its supporting post 1. Inasmuch as both f the gates are of'the same construction it Will be found that the springs 9 thereof will Hold the gates normally together attheir ildJOlIling ends, said ends being located above the center of the track The rods 3 and the eyes 5 serve to properly support the gates while in this position.

7 A rod 10 extends transversely through the gated. and engages one of the rods 8 thereof, this rod 10 being arranged parallel with the track '2 and having each end engaged by the upper slotted end 11 of a lever 12. Said lever projects under the track 2 at a point removed some distance from the gate and is pivotally mounted upon a bracket 13 located under the track. A frame B- is located between the rails of the track and the side strips 1-L of this frame two wheels of a car are always in position above the frame.

As has already been pointed out the gates A are normally closed as shown in Fig. 1, and, when they are thus located, the frame B lies with the upper faces of its side strips 14 in substantially the same horizontal plane as the tops of the rails '2. Chen a train approaches the guard the flanges of the wheels of the cars ride onto the side strips 14 of the frame B and force said frame downward. mitted through the hangers 15 to the levers 12 and said levers are simultaneously swung laterally so as to press the rods 10 in the direction of the posts 1. Inasmuch as these rods are attached rigidly to the gates A said gates will also be shifted toward the posts and will be held in these positions as long as the frame B is depressed. The train can thus pass between the open gates and as soon as it leaves the depressed frame B, the said frame and all of the balance of the mechanism will be returned to their initial Motion is thus transiii Q g a eezeee positions by the springs 9 which, as will be toward the standard said standard having guide eyes, a gate shdably mounted witlnn the standard and eyes and upon the rods, a spring connected to one end of the gate and to the standard and constituting means I for holding the gate normally projected over the track, a depressible frame located between the rails of the track, a hanger connected rigidly to the frame and extending into the pit, a lever fulcrumed Within said pit and pivotally and ,slidably engaging the hanger, said lever extending above the pit and having a longitudinal slot, and means upon the gate and projecting into the slot for transmitting motion from said lever to the gate, said gate when shifted by the lever, being adapted to place the spring under stress.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature'in the presence of two witnesses.
